Induction Brazing Steel Tips with Hihg Frequency Heating System

Objective To heat a steel tip and shank assembly to 1300°F (704°C) within 3 seconds for brazing with induction heating instead of torch brazing.
Material 0.1” (2.54mm) diameter steel tip & shank, 0.07” (1.78mm) diameter braze ring
Temperature 1300°F (704°C)
Frequency 800kHz
Equipment DW-UHF-4.5kW induction heating system, remote heat station containing one 1.2 microfarad capacitor.
Process A two turn helical coil is used to braze the dental parts. The braze ring is placed at the joint area of the steel tip and shank. Black flux is applied to the joint area. RF power is applied for 3 seconds to heat the parts to the established target temperature and the braze paste flows evenly and consistantly.
Results/Benefits Induction heating provides:
• Fast, accurate, repeatable heat
• Ability to heat very small areas within precise production tolerances
• Better joint quality, reduced oxidation
• Increased production rates and reduced labor costs
